Assignment description

• The objectives of this part of the coursework are to capture and analyze remote ICMP Data in Wireshark. Wireshark is a software protocol analyzer, or "packet sniffer" application, used for network troubleshooting, analysis, software and protocol development, and education. As data streams travel back and forth over the network, the sniffer "captures" each protocol data unit (PDU) and can decode and analyze its content according to the appropriate RFC or other specifications. You are to ping a remote host (host not on the LAN) and examine the generated data from this ping. Explain what would be different about this data from the usual data in LAN. Ping the following website www.reading.ac.uk (set the number of ping requests to 4). You then examine IP and MAC addresses and analyze the data from the remote host. What is significant about this information, does Wireshark show the actual MAC address for the remote host. your reflection about the MAC address in terms of the local host.
• A packet tracer is a simulation tool that helps to configure and visualize a network in logical and physical modes. The objective is to configure a small office Local Area Network (LAN) where 5 PCs and 1 printer are connected to a wireless router through wires. 1 mobile and 1 tablet PC are connected to the same wireless router which is acting as a DHCP server and default gateway provided by Internet Service Provider (ISP) to connect all those devices to the internet.

Configure those devices with the IP addresses

Default gateway- 192.168.1.1/24

Reserve IP addresses for those devices through DHCP

PC1- 192.168.1.10/24

PC2- 192.168.1.11/24

PC3- 192.168.1.12/24

PC4- 192.168.1.13/24

PC5- 192.168.1.14/24

Printer - 192.168.1.253/24

Wireless Router configuration would be - SSID- pollyvacherwireless, with WPA2 Enterprise AES with shared key - P0llyVch3r. (Hint: you may need to set up a Radius AAA server). You then test at least two pairs of device-to-device connections using proper networking command(s) and check that different device can communicate with each other.

• Install 1 DNS Server (192.168.1.2/24) and 1 HTTP server (192.168.1.3/24) into the previous office network. Update the DHCP configuration to reserve IP addresses for the new servers. On the DNS Server, add an A record mapping between www.pollyvacher.ac.uk and the HTTP server. Test the DNS resolution for www.pollyvacher.ac.uk using proper networking command(s) on at least 1 PC and 1 mobile device. Finally, use the web browser to open www.pollyvacher.ac.uk on at least 1 PC and 1 mobile device.

Submission requirements -

• Introduction
• Use of Wireshark for packet sniffing. It's essential to include evidence (e.g., screenshots) of the testing carried out after the implementation of the ICMP protocol.
• A small office network implementation .pkt file, network overview, and screenshots should be provided along with discussions. You should include as minimum screenshots of the network diagram, DHCP configuration (router), Wireless Security (router), AAA configuration (Radius server), DNS configuration (DNS Server), and HTTP configuration (HTTP server).
• A discussion, a short conclusion, and your personal reflection on this project.

Here is the Self assessment requirement form.
